BUCKLE.

SPECIFICATION forming part of Letters Patent No. 396,266, dated January15, 1889.

Application filed October 31, 1888. Serial No. 289,662- (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES D. CHEESMAN, a citizen of the United States,residing at Birmingham, in the county of New Haven and State ofConnecticut, have invented new and useful Improvements in Buckles, ofwhich the following is a specification.

My invention relates to that class of buckles used for suspenders andlike purposes, and which are usually made to surround the sus pender,the clamp being inserted through a slot upon one side and caused toengage the suspender by a bearing upon one side and caused to engage thesuspender by a bearing upon the opposite side of the surrounding orincasing portion.

It is the purpose of my invention to provide a simple and improvedconstruction whereby increased strength and rigidity are imparted to thebuckle and the clamping strain removed from the front plate thereof, andwhereby, also, the construction of: the buckle-frame, or that portionsurrounding the suspender, is simplified and cheapened.

To this end my invention consists in the several novel features ofconstruction and new combinations of parts hereinafter fully set forth,and then definitely pointed out in the claim following thisspecification.

In the accompanying drawings, Figure 1 is a perspective view of a buckleembodying my invention. Fig. 2 is a horizontal section of Fig. 1. Fig. 3is a detail view of the component part-s of the buckle separated fromeach other. Fig. l is a detail view showing the manner of fastening theparts.

In the said drawings, the reference-numeral 1 denotes the frame of thebuckle, which is formed in two parts, one of said parts, 2, constitutingthe front plate of the buckle-frame, and the other part, 3, forming theback of said frame. The front plate, 2, may be made of any suitablemetalsuch as brass-its ends 4L being turned at right angles, orsubstantially so, to the body of the plate, to form flanges ofsufficient length to overlie or partly cover the The back plate, 3, mayalso be made of any suitable metal, and its ends 5 are also turned atsubstantially right angles to the body of the plate, but are of suchlength that their extremities 5 are further bent into parallelism withthe body of the front plate, upon which said extremities lie, overlyingthe ends of the body of the front plate by a short distance, as seen inFig. 2. The parts are so constructed and arranged that the bent ends ofthe front plate lie outside the bent ends 5 of the back plate. The twoparts of the frame are united either by solder, by rivets, or byindenting the metal forming the overlappings ends 4 and 5, as shown at6, Fig. 4. In some respects this latter form of fastening is to bepreferred.

The buckle-frame thus constructed forms a flat tube adapted to in closethe suspender, but capable of sliding freely thereon. In the body of thefront plate, 2, is formed a slot, 7, through which the clamping-lever isintroduced. This lever is of the usual. construction in all essentialparticulars, and is provided with pintles By the construct-ion describednot only are the strength and rigidity of the buckle-frame increased,but the entire bearing of the clamping-lever and the wear of theclamping pintles or shoulders are thrown upon the laterallybentextremities 5" of the ends of the back plate.

By my invention I am enabled to form the back plate of iron or otherinferior and cheap metal, while the front plate may be made of a costlymetalsuch as rolled goldand as the back plate takes up substantially allthe strain of the clamping-lever I can make the front plate of very thinstock.

In the manufacture of the buckles the hooked end of the clamping levercan be forced through the slot 7 from the inside of the front plate, 2,since the metal is sufficiently flexible to permit the lever to beapplied in this way, if desired. construction that the back plate haveits extremities bent toward each other, so as to hug and overlie the endportions of the body of the front plate which carries the clampinglever, for by this means strain on thefront plate, incident to itscarrying the lever, is taken up and borne by those portions of the backplate that overlie and bear against the inside of the frontlever-carrying plate. Be-

sides this bracing-support of the front plate and bearing of the strainthereupon, the improved construction permits me, if desired, to unitethe front and back plates by a simple indentation at each end.
